Answer:
8 cubic feet
Step-by-step explanation:
First find the volume of the sand box
2 x 2 x 3 = 12
then multiply the total volume by 2/3
12 x 2/3 = 8
That leaves you with the total cubic feet of sand he would need.
Answer:
Step-by-step explanation:
because The curve C crosses the x-axis at the origin and at the points A and B => the x coordinates of A and B are the solution of the equation:
x(x + 4)(x - 2) = 0
<=> x = 0
x = -4
x = 2
because the x-coordinates of the points A and B aren't 0 and the x-coordinate
of A is a negative value
=> the x-coordinate of A is -4
the x-coordinate of B is 2

Answer:
Step-by-step explanation:
Given that X is N(50,3)
So whenever we want score for x, we can convert this to Z and use std normal distribution table.
The formula for conversion is
Using this we can find out the corresponding scores
a) 
Z value = 1 and hence
b) 
c) 
d) 
e) 10th percentile is 
f) This is 99th percentile
=
Answer:
f(x) = 2+√x
Step-by-step explanation:
To shift a function up by k units, add k to the value of the function. Here, you want to shift the square root function up 2 units, so you add 2 to the square root:
f(x) = 2+√x
